BREWER, Maine — The girls who handed out free hot chocolate to motorists passing their Bowdoin Drive home while looking at Christmas lights doubled what they raised last year for the Cystic Fibrosis Foundation.

“We raised over $4,600, which is going to help the fight against cancer and cystic fibrosis,” said Mike Openshaw, the father of three of the girls — Abby Sargent, 8, Jessica Sargent, 10, and Torri Openshaw, 9.

Openshaw said his girls decided also to raise money to fight cancer after he was diagnosed in July with metastatic pheochromocytoma, a rare form of neuroendocrine cancer.

In addition to cousins who showed up to help, this time around other kids from around the neighborhood also got involved, he said.

When a man arrived and gave the group an envelope with a $1,000 donation from Bangor Savings Bank, he drove away without saying a word.

“There were a lot of happy tears” when volunteers discovered what was inside, Openshaw said.
